A 36-gene predictive score of anti-cancer drug resistance anticipates cancer therapy outcomes

A 36-gene predictive score of anti-cancer drug resistance anticipates cancer therapy outcomes
2024-11-07
BIRMINGHAM, Ala. – In 1937, President Franklin Roosevelt signed the National Cancer Act, launching a nationwide effort to combat the disease. Eighty-seven years later, despite significant progress, cancer treatment often falls short, with 50 to 80 percent of patients not responding to treatment and more than 600,000 cancer deaths annually in the United States. What if clinicians could predict the success of any cancer treatment, ensuring each patient receives the most effective care? The challenge lies in the diverse nature of the disease. There are hundreds of different types of cancers, characterized by the specific type of cell from which they originate. Even patients ...

2024-11-07
Picture this: You’re at a bar when someone starts hitting shamelessly on your spouse or significant other, who doesn’t flirt back. As the scene unfolds, your base instincts kick in—annoyance, anger, jealousy—followed by a heightened sexual desire for your partner. You’re ready to reclaim the attention that should be rightfully yours, correct? Not necessarily, according to a new study in the Journal of Sex Research by researchers at Reichman University in Herzliya, Israel, and ...

Hourglass-shaped stent could ease severe chest pain from microvascular disease

2024-11-07
ROCHESTER, Minn. — A study at Mayo Clinic suggests that an hourglass-shaped stent could improve blood flow and ease severe and reoccurring chest pain in people with microvascular disease. Of 30 participants in a phase 2 clinical trial, 76% saw improvement in their day-to-day life. For example, some participants who reported not being able to walk around the block or up a flight of stairs without chest pain were able to do these ordinary physical activities at the end of a 120-day period. Clinical measures of blood flow related to the microvasculature of the heart significantly improved during ...

Could crowdsourcing hold the key to early wildfire detection?

2024-11-07
The 2023 blaze in Lahaina, Hawaii, which claimed more than 100 lives and burned 6,500 acres of land across Maui, is a tragic example of how rapid wildfire spread can make effective response efforts impossible, resulting in the loss of life and property. What if technology could help people detect wildfires earlier? The solution could already be in your pocket: a mobile phone. USC computer science researchers have developed a new crowdsourcing system that dramatically slashes wildfire mapping time from hours to seconds using a network of low-cost mobile phones mounted on properties in high fire threat areas. In computer simulations, the system, FireLoc, detected blazes igniting ...

The system addresses a critical challenge for sustainable water and oil reclamation across various industries. Separating oil and water from complex mixtures is essential for many scientific and industrial applications, such as wastewater treatment and biological sorting. Membrane ...

COVID-19 restrictions altered global dispersal of influenza viruses

2024-11-07
Although travel restrictions and social measures during the COVID-19 pandemic led to a dramatic global drop in seasonal influenza cases, certain influenza lineages in specific regions kept the virus circulating and evolving, according to a new study. This was true in tropical areas with fewer travel restrictions, for example, including South and West Asia. The spread of seasonal influenza is closely tied to social behavior, particularly air travel, and to the periodic evolution of new virus strains that evade immunity from prior infections or vaccinations. In 2020, nonpharmaceutical interventions (NPIs) introduced to combat COVID-19 – such as ...

Disconnecting hepatic vagus nerve restores balance to liver and brain circadian clocks, reducing overeating in mice

2024-11-07
Disruptions between the brain’s master circadian clock and the liver’s internal clock, communicated via the hepatic afferent vagal nerve (HVAN), can lead to unhealthy eating patterns and increased weight gain, according to a new study in mice. The findings identify the neural link as a potential therapeutic target for obesity and metabolic dysfunction related to circadian disruption. In mammals, circadian rhythms are controlled by the suprachiasmatic nucleus (SCN) – a small part of the brain’s hypothalamus that regulates the body’s circadian rhythms. This cycle triggers a feedback loop involving key clock genes that keep ...

Mechanosensory origins of “wet dog shakes” – a tactic used by many hairy mammals – uncovered in mice

2024-11-07
“Wet dog shakes” – a common reflex behavior shared among many hairy mammals and designed to expel water and irritants from their coats – happens when particular mechanoreceptors are activated, researchers studying mice report. Many furry mammals engage in rapid body twists known as "wet dog shakes" to effectively remove water from their fur, as well as to eliminate irritants like tangles or parasites, particularly in areas on the neck and back that are largely unreachable by self-grooming or licking. However, despite the commonality of this behavior ...

New study links liver-brain communication to daily eating patterns

2024-11-07
PHILADELPHIA— People who work the nightshift or odd hours and eat at irregular times are more prone to weight gain and diabetes, likely due to eating patterns not timed with natural daylight and when people typically eat. But is it possible to stave off the ill effects of eating at these “unusual” times despite it not being biologically preferable? A new study from the Perelman School of Medicine at the University of Pennsylvania says ‘yes’, and sheds light on how the body knows when to eat. The study, published today in Science, explains how researchers discovered a connection between the liver's internal clock and feeding centers in the ...

Defense or growth – How plants allocate resources

2024-11-07
The more a plant species invests in defense, the less potential it has for growth, according to a new study. Research made possible by open science provides new insights into plant adaptation and interspecies variation. Pathogens can significantly weaken the fitness of their hosts, sometimes even causing host mortality. Yet considerable variation is found between species in their investment in disease defense. Evolutionary theory predicts that allocation costs regulate this investment, but testing this hypothesis ...

The aim of the study was to establish hip implant materials at risk of revision to help orthopaedic surgeons, and patients, and to improve shared decision making ...

Study reveals how plants grow thicker, not just taller

Study reveals how plants grow thicker, not just taller
2024-11-07
Most research on plant stem cells focuses on the tips of roots and shoots, where growth occurs in height. But Ten Tusscher explains that thickness growth is just as essential. “Plants can’t grow endlessly in height. They also need to grow in thickness, or they would simply fall over,” she says. The growth in thickness, is what makes older trees visibly thicker and more robust over time. This growth is essential for structural strength, particularly in trees. Stem cells in the plant’s cambium layer control this width growth, producing wood to support the plant’s structure. However, which genes enable these cambium stem cells to become active ...

Insect-killing fungi find unexpected harmony in war

Insect-killing fungi find unexpected harmony in war
2024-11-07
University of Maryland entomologists uncovered a unique relationship between two species of fungi known for their ability to invade, parasitize and kill insects efficiently. Instead of violently competing for the spoils of war, the two fungi peacefully cooperate and share their victims. The findings, published in the journal Public Library of Science (PLOS) Pathogens on November 7, 2024, offer insight into some of the biggest evolutionary successes in nature’s history, according to study co-authors Raymond St. Leger, a Distinguished University Professor of Entomology, and entomology Ph.D. candidate Huiyu Sheng. “It’s not survival ...
